BOBBIN-HANDLING MACHINE.

Application filed May 12,

This invention relates to improvments in bobbin handling machines and is'directed more particularly,- to improvements in machines of the class described in U. S. Letters Patent 1,556,4t69' issued to me October 6,

By reference to the patent referred to, it will be observed that the bobbins are delivered one by one onto the receiving spindles ofa rotatingcarrier. If the bobbins are defective by being warped, they will not slip entirely onto the said spindles and will project therefrom to act on certain mechanism so that the machine will be stopped thereby to allow the operator to remove such defective bobbins from the spindle, While such perfect bobbins as are received-by the spindles will be delivered to a receptacle below which is provided therefor.

The principal object of this invention is the provision of mechanism for use in conjunction with machines similar to that referred to for ejecting warped bobbins or bobbins having undersized openings from the spindle into a receptacle, the said mechanism being adapted and arranged to operate with-- out stopping the machine, whereby the delays caused by defective bobbins may be entirely eliminated.

Other objects and advantages of the invention and the novel features of construction thereof will be apparent from the following description which is illustrated in the form at present preferred by means of the accompanying drawings in which:

Fig. 1 is a side elevational view partly in section showing the mechanism for ejecting a warped bobbin from a spindle of a carrier;

Fig. 2 is a plan view taken on theline 22 of Fig. 1; and I a Fig. 3 is an enlarged perspective view of the ejector actuating lever.

Referring to the drawings in detail, a carrier wheel 1 having bobbin receiving spindles 2 is rotated in a step by step manner on a shaft S by means ofa Geneva 3 actuated by a Geneva crank or driver 4 fixed on a shaft 5 which is geared to and driven from a shaft 6. This mechanism is similar tothat shown and described in the patent referred to and.

will similarly function to rotate the'carrier wheel in a, counter-clockwise direction. This movement will carry the bobbins received on 1926. Serial No. 108,686.

the spindles'whe-n in the top center-position around to a point where they fall by avitytherefrom and into a receptacle 7" t erebelow, provided, of course, such bobbins are straight-and unwarped so as to slip easily over thespindles. I

The. bobbins may be released one 'b' onefrom a spout and' delivered onto the spindles in their top center position by means of the mechanismshown and described in thebefore-mentioned patent. unwarpe-d and straight and are provided with suitable sized bores, theywill' slip entirely over the spindlesand rest on thecarrier and as the spindle is carried into downwardly inclined positions, the bobbin will slip or fall therefrom into-a receptacle 7. Should a bobbin that is either warped or has an undersized bore be delivered onto the spindle, then obviously itwill not-properly slip over the spindle and will project beyond the end thereof 'as shown i-n dotted lines at B. This imperfect bobbin it is desired to separate from the perfect ones delivered to the receptacle 7 andtoaccomplish this I- provide the novel mechanism forming a part of this invention and nowto; be described.

A detector lever oscillatable'onthe shaft has a bifurcated or forked upper arm 11 and a lowerarm 12.; A roll or pin 13 carried at the extremity of the arm 11 is arran ed to lie in the'path of 'any defective bob in that extends beyond the end of'its s indleas shown, and as the roll is engaged y the end of the bobbin in its rotation, the armwill beswung downwardly thereby.

A control lever-14' pivotedat 15 is con.- nectedby a suitable rod 1 6 to "the arm-12 of the lever just described and is swung thereby j to the right when an imperfect bobbin strikes the detector lever; 11. An impulse lever17 pivoted at 18 to a suitablesupport 10 has a cam shaped lower end 18' arranged" thereon for a 'hinged or swinging action' in a plane transversely to the swinging movement, of the lever and is arranged to 'bemoved into'and out of thepath of a pin or roll 19- carried. by a crank 20 fixed to the continuously rotating shaftG. ,7

A- control rod 21 fixed to" the upper end of control lever '14 is slidable in a guide 22 carriedby the hinged cam end l8' ofthe If the bobbinsfare lever 18 and is offset substantially in a horizontal plane, as best shown in Fig. 3. This rod is preferably so arranged that it will, when it is reciprocated through the guide, move the cam end 18 into and out of the path of'the roll 19 accordingly as the lever 14: is rocked in one direction or the other.

An operating lever 23 pivoted at 24k to the support 10 is also pivotally connected at its upper end to the upper end of the im pulse lever 17 While its lower end is likewise pivoted to an ejector member E which is slidable along the arm 11 of the detector lever. The ejector E is provided at its forward end with downwardly depending guides in the form of rolls 25 which work in connection with the bifurcated arm to guide the same therealong. As shown in Fig. 2, the ejector E is provided with a laterally extending lug or ledge 26 which is dis posed and arranged to strike against the lower end of a bobbin on the spindle and will in its reciprocating movement along the lever arm 11 eject a bobbin from theSpindle and into a chute C which is disposed so as to have its delivery month over a receptacle 27 therebelow for receiving rejected orimperfect bobbins. Means are provided for returning the parts to the position shown after each ejecting operation and may comprise springs 30 and 32, as shown, arranged to pull the levers 17 and 14- into engagement "with the stops 31 and 33.

In operation, when for any of the reasons before mentioned, a bobbin such as indicated at B does not slip entirely over the spindle and projects therebeyond, it will, as it is carried by the wheel, strike the roll 13 of the arm 11 and move said arm downwardly. This movement will shift the control lever 14 to the right and the rod 21 thereof will locate the cam end 18 of the lever 17 in the path of the rotating roll 19. The cam end 18 will be engaged by the roll 19 of the crank 20 and will be swungsquickly in a counterclockwise direction. This movement will impart a swinging movement to the ejector operating lever 23 so as to move the ejector E up along the arm 11 whereby the ledge 26 of the ejectorwill engage the bottommost or rear side of tne bobbin and eject it from the spindle into the chute C. The springs 30 and 32 will quickly return the parts to their inoperative position shown for a subsequent 'ej ecting movement.

Ordinarily properly sized or perfect bobbins are carried by the spindle until they fall therefrom into the receptacle, but in case they should not fall readily therefrom, I provide a means to positively remove them from the spindlewhich comprises the following.

A cam member 34 adjustably mounted on a bracket 35 is disposed adjacent the rotatable carrier and has a curved outer periph.

eral face 32 preferably arranged in'an eccentric relation with the axis of rotation of the carrier. As the bobbins are rotated past the cam 34;, its face 34 will engage with the lower or bottom end of the bobbin and gradually cam it from the spindle durlng the rotation of the carrier and thereby insure that all spindles are empty when they arrive at their top center or bobbin receiving position.

From the above, it will be observed that I have provided means for ejecting imperfect bobbins from the spindles of the carrier departing from the scope thereof and I prefer to be limited by the appended, claims rather than by the foregoing description. I
